Hi Lenya devs, we have a problem in the current transaction handling.
Imagine the following scenario: - A document is in the workflow state "authoring". - Alice invokes a usecase which alters the workflow. - The menubar is displayed on the workflow screens. - The usecase comprises several steps, it is committed only after the last step. - On the second screen, the workflow state of the document has already been changed to "review". - This means that the menu item "publish" can be invoked, because the identity map is attached to the request and accessed by all components (no isolation of the active usecase). - Invoking the menu item results in an error because the usecase hadn't been committed. I see two solutions: a) Do not allow to show the menu during usecase execution (equivalent to a model dialog box). b) Don't access the repository documents via sources, but directly (a separate repository session for the active usecase). The RepositorySource wouldn't implement ModifiableSource anymore. IMO (a) is just a workaround, (b) is the way to go.
